Excuse me .   Yes ? What can I do for you ?   I just checked in , and there's a problem with my room .   And what is the problem ?   I asked for a non-smoking room , and I don't have one.My room smells like cigarette smoke . I can't stand it.Could you change my room , please ?   Let me see ... I'm sorry , but we don't have any more non-smoking rooms.We won't charge you for your room tonight .   Thank you .   I'm very sorry about this .   That's OK . Thanks for your help .
